This is a template filter to enable the use of the MEDIA_URL setting in content from the flatpages database table. It searches for {{ MEDIA_URL }} and replaces it with that found in your settings.

Note: To set up, drop the above code into a file called media_url.py in your templatetags directory in one of your INSTALLED_APPS, and add the filter to your flatpages template like so:

{% load media_url %}
{{ flatpage.content|media_url }}

@register.filter
@stringfilter
def media_url(value):
    """Searches for {{ MEDIA_URL }} and replaces it with the MEDIA_URL from settings.py"""
    return value.replace('{{ MEDIA_URL }}', settings.MEDIA_URL)
media_url.is_safe = True

@kylefox: I think you missed the point of this snippet... since the content comes from the database via flatpage's content field, the interpretation of any Django template code doesn't happen -- it only happens on actual templates themselves. Since this is content being displayed in the template, Django isn't going to run the content through a Template processor.

So all this snippet does is search and replace {{ MEDIA_URL }} in the content with its appropriate setting value. A context processor isn't going to be able to do that.
